Kyle Busch remained perfect in NASCAR Truck Series racing Friday, winning his fourth race in as many tries this season in the Lucas Oil 200 at Dover International Speedway.

Count the final race of 2013 in Homestead, Fla. – which he also won – and it’s five truck victories in a row for Busch.

“I don’t know if it’s anything I’m doing in particular to win these races,” said Busch. “We’re tweaking some things. We don’t unload and expect to win. We unload and get the car to drive well and go on that.”

It was Busch’s 39th career win in a truck, second on the all-time list behind Ron Hornaday’s 51.

Ryan Blaney finished second with Johnny Sauter third.

Pre-race points leader Matt Crafton, who was racing with Busch for the lead for much of the day, hit the wall on Lap 157 when his right-front tire went down. That ended things for Crafton, whose last did-not-finish came when he crashed in the season-opening race at Dayton in 2012 – 47 races ago. He finished 23rd and dropped into a tie for second with Sauter, one point behind new-leader Timothy Peters, who finished 10th.

“Matt was really good today,” said Busch. “It’s a shame he had his troubles and got knocked out of the race. It looked like a really hard hit. Those are hits you don’t want to see guys go through.”

Busch, who splits time in the No. 51 Toyota with Erik Jones for the Kyle Busch Motorsports team he owns, also won five straight races in 2009. Busch won’t race again in the truck series until Kentucky later this month.

“I told Erik just because the name changes on the roof, it doesn’t mean he can’t end up in victory lane,” said Busch.

But having Busch in the car makes the No. 51 much more formidable.

“His organization made a lot of gains over the winter,” said Sauter. “But we’ve beaten them before. It doesn’t bother me at all. They’re doing it right. They’ve just got fast trucks now.

“Kyle is a great race-car driver, we all know that. But we also know he’s not unbeatable.”
